[6][7] Distraught, Yuriko belatedly embraced her father's ideals and sought to track down whoever dishonored him and restore Japan's honor.

[8] She went to the Mojoverse and sought Spiral's "body shoppe" where she received extensive cybernetic enhancements including adamantium bones and talons.

[9] Lady Deathstrike – along with Cole, Macon, and Reese – joined the team of criminal cyborgs called the Reavers, led by Donald Pierce.

[13] At times she has resigned her quest to kill Logan and has worked cooperatively with the X-Men toward a common goal, such as the defeat of Stryfe.

When Captain America appears in Japan after a year spent in another dimension, he manages to find Lady Deathstrike working with terrorists.

[16] She displays a new ability to access the Internet via her cybernetics but this led to her being co-opted and controlled by Mount Haven's computer systems.

[18] Following her confrontation with Rogue and Sunfire, Lady Deathstrike resurfaced as a member of one of the United States government's Army of Thunderbolts in the super hero Civil War, temporarily released from prison in order to go after the Secret Avengers, who resisted the Superhuman Registration Act.

[21] This was confirmed by IGN Comics, who, in their editorial analysis "13 Days of Messiah Complex," revealed that Deathstrike would be leading a new team of Reavers throughout the event.

[22] As reported, Lady Deathstrike appears alongside the Reavers, now made up of nameless Purifiers with armor and weapons instead of any former members.

She then traveled to the Jean Grey Academy alongside her friend Reiko to find Karima Shapandar and retrieve the Omega Sentinel technology.

[44] Lady Deathstrike recovers and continues her fight with her father until Lord Dark Wind cuts off her left hand.

[47] Psychologist Suzana E. Flores argues that Lady Deathstrike evinces traits of obsessive compulsive disorder in her drive to obtain Wolverine's adamantium.

As Flores characterizes it, Lady Deathstrike "'needs' the adamantium to credibly establish or validate her self-worth," but even if she were to achieve this, her personality would lead her to "find some other victim or idea over which to obsess.

"[48] Lady Deathstrike was transformed into a cyborg by Spiral and the "Body Shop" using alien technology of Mojo's dimension,[9] with later modifications by Donald Pierce.

Lady Deathstrike is incredibly qualified with swords, and while she prefers stealth and subtlety in her killings, she is emotionally disturbed, which interferes with her effectiveness.

[volume & issue needed] Before she received her cybernetic enhancements, Deathstrike used a special five-foot steel katana that was electromagnetically tempered and sheathed in energy.

She has also used shuriken, nunchakus, a high-powered, long-range blaster that fires armor-piercing explosive bullets, and wristbands containing adamantium detectors.

[volume & issue needed] Deathstrike later received an upgrade that provides her with a kind of "cybernetic healing factor" that functions similarly, although not as efficiently, to Wolverine's.
